New Features Introduced in A.10.32

+Odataprefetch — to generate data prefetch instructions for data structures referenced within innermost loops.

+Oentrysched — changing to make save and restore operations more efficient.

+Ofailsafe — to enable fail-safe optimization by default.When a compilation fails at the current optimization level, +Ofailsafe will automatically restart the compilation at a lower level of optimization.

+Ofltacc — to provide better performance for PA-RISC 2.0 targets.

+Oglobal_ptrs_unique — to tell the optimizer whether there are unique global pointer variable names, and what the names are.

+Oinline_budget — to perform aggressive inlining.

+Oloop_unroll — to enable loop unrolling.

+Optrs_ansi — to assume that an int *p points to an int field of a struct or union, and that char * points to any type of object.

+Optrs_to_globals — to tell the optimizer whether global variables are modified through pointers.

+Optrs_strongly_typed — to assume that all pointers are type safe.

+Ostatic_prediction — to enable static branch prediction.

+Owhole_program_mode — to hold global variables in registers longer and delete inlined or cloned global procedures.

+ESfic option — to replace millicode calls with inline code for fast indirect calls.

Enhancement to optimization levels 2, 3, and 4 to enhance performance of programs including macro definitions of ABS, MIN, and MAX.

New +DA designations for PA-RISC 2.0 model and processor numbers to generate code for the PA-RISC 2.0 systems. Also a +DAportable option to generate code compatible across PA-RISC 2.0 and 1.1 workstations and servers. Default architecture object code generation is now determined automatically on all systems as that of the machine on which you compile.

New +DS designations for PA-RISC 2.0 model and processor numbers to perform instruction scheduling tuned for PA-RISC 2.0 systems. Default instruction scheduling is now determined automatically on all systems as that of the machine on which you compile.

3 location tracking mappings between source lines and object code locations. Single-stepping and breakpoint setting supported for 3 models of location mappings.

Breakpoints and single-stepping based on Source Statement Order and Statement Completion location mapping models.

Assembly level debugging incorporating the new Statement Completion model and enhancements to the statement fragment model.

Tracking updates of user variables in assignment statements using new statement completion UI commands.

Notification when variable values are unavailable, or the accuracy of the data value is questionable due to optimization.

Viewing locals, globals, and parameters within procedures, for variables which are active and have not been eliminated due to optimization.

Notification of out of order updates to user variables using the Source Order model.

Identical program behavior between programs compiled with and without debug.

Tracebacks with line-number annotations.

Setting breakpoints and single-stepping at the source statement level.

Viewing and modifying global variables and parameters at procedure entry.

HP C/HP-UX now includes a +help option to invoke online help for the HP C compiler and linker.

Note that when code is ported from a PC to a workstation, a carriage return in the PC code is converted to a newline on the workstation. Control M is ignored by cpp.

The compiler is now large file aware and will give you the following message if your source file is larger than 2 GB: Can't open filename.
